模拟泥石流中块状物分布的电容层析成像测量
Imaging of solid blocks in the mimic debris flow using electrical capacitance tomography
摘要
Abstract
Electrical capacitance tomography (ECT) is a process tomography ( FT) based on capacitance sensor, which is one of the outstanding multi-phase flow measurement technologies. In this paper, ECT system was used to visualize the location of solid block in the mimic debris flow. High-viscosity fluid was used to simulate the debris flow. At the same lime, the spherical and cylinder vessel in which alcohol and sediment were built were used to simulate the solid block in the mimic debris flow. Double-layer sensors were designed to acquire the solid block distribution and movement velocity in the mimic debris flow. Cross correlation method was adopted in the movement velocity calculation process. This research provides a reasonable and effective way for debris flow field.关键词
